We study strategic games where players' preferences are weak orders which need not admit utility representations. First of all, we extend Voorneveld's concept of best-response potential from cardinal to ordinal games and derive the analogue of his characterization result: An ordinal game is a...

The “Coase theorem” is made of the efficiency and the neutrality theses. Using cooperative game theory, we show that these two theses are not compatible: there exist only two types of rights assignments that guarantee a nonempty core. Thus, the efficiency thesis holds – there exist (two...

A new model of strategic networking is developed and analyzed, where an agent’s investment in links is nonspecific. The model comprises a large class of games which are both potential and super- or submodular games. We obtain comparative statics results for Nash equilibria with respect to...
